Nikolai Kakhidze, mudzidzi akapedza kudzidza kuFaculty of Physics and Engineering, akurudzira kushandisa diamond kana aluminium oxide nanoparticles seimwe nzira yekudhura scandium yekuomesa aruminiyamu alloys. Iyo nyowani inodhura yakapetwa ka4 pane iyo scandium-ine analogi ine yakanyatso kuvharika yemuviri uye yemagetsi zvivakwa.
Parizvino, makambani mazhinji ekuvaka ngarava ari kuedza kutsiva simbi inorema nemwenje uye ultra-light materials. Pamusoro pekuwedzera kutakura kutakura, izvi zvinogona kushandiswa zvine mutsindo kuderedza kushandiswa kwemafuta, kuderedza kuburitsa kunokuvadza mumhepo uye kuwedzera kufamba kwechikepe uye kukurumidza kutakura zvinhu. Mabhizinesi mune zvekutakura uye maindasitiri emuchadenga anofarirawo zvinhu zvitsva.
Aluminium matrix composite zvinhu zvakagadziridzwa ne scandium yakava inotsiva yakanaka. Nekudaro, nekuda kwemutengo wakakwira we scandium, kutsvaga kunoshanda kuri kuitika kune inodhura inogadzirisa modifier. Nikolai Kakhidze akaronga kutsiva scandium nedhaimondi kana aluminium oxide nanoparticles. Basa rake richava rekugadzira nzira yekusuma kwakaringana nanopowder musimbi inonyungudika.
Kana yanyatsopinzwa mukunyungudika, iwo nanoparticles anounganidzwa kuita agglomerates, oxidized, uye asina kunyorova, uye anoumba pores akazvitenderedza. Somugumisiro, tsvina isingadiwi inowanikwa panzvimbo yekuomesa zvimedu. Murabhoritari yemhando yepamusoro-simba uye yakakosha zvinhu paTomsk State University, Sergey Vorozhtsov akatogadzira nzira dzesainzi uye tekinoroji dzekupararira kuomeswa kwealuminium uye magnesium inovimbisa kuiswa kwakaringana kwerefractory nanoparticles mukunyunguduka uye kubvisa matambudziko ekunyorova uye kuyerera. .
- Zvichienderana nekuvandudzwa kwevamwe vandinoshanda navo, chirongwa changu chinopa mhinduro inotevera: nanopowders inoparadzaniswa (yakagoverwa zvakaenzana) mune micro-sized aluminium poda uchishandisa akati wandei tekinoroji mashandiro. Ipapo ligature inogadzirwa kubva musanganiswa uyu wakakwana tekinoroji uye yakanakira kushandiswa kwemaindasitiri pachiyero cheindasitiri. Kana iyo ligature inounzwa mukunyunguduka, minda yekunze inogadziriswa kuti iparadze zvakafanana nanoparticles uye kuwedzera kuwedzera kunyorova. Kusuma kwakarurama kwe nanoparticles kunogona kuvandudza maitiro emuviri uye emagetsi ekutanga alloy, - Nikolai Kakhidze anotsanangura chinangwa chebasa rake.
Nikolai Kakhidze anoronga kugamuchira mabheti ekutanga ekuedzwa kwe ligatures ane nanoparticles nokuda kwekutsvaga kwavo kunotevera mukunyunguduka pakupera kwa 2020. Muna 2021, inorongwa kuwana kutongwa kwekutongwa uye kuchengetedza kodzero dzepfungwa dzepfungwa.
